  • Patent number: 10968696
    Abstract: A battery-powered window treatment, such as a roller shade, may include a battery compartment that provides access to batteries while the window treatment is assembled and mounted to a structure. The battery compartment may be pivotally supported by a housing of the window treatment, and operable between opened and closed positions. The batteries may be concealed when the battery compartment is closed, and may be accessible when the battery compartment is open. The battery compartment may be operated opened and closed while a shade of the window treatment is at any position, such that removal of the batteries does not result in the loss of tracking information for the shade. The window treatment may include a fascia that is operably connected to the battery compartment, such that when the battery compartment is opened, the fascia does not obstruct access to the batteries, and does not interfere with the shade.

  • Publication number: 20210002954
    Abstract: A motorized window treatment for controlling the amount of daylight entering a space through a window includes a covering material, a drive shaft, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions to minimize motor usage and conserve battery life. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors, or in response to an infrared or radio-frequency remote control.

  • Patent number: 10840691
    Abstract: Systems and methods to detect Automatic Lateral Switch operations. Power down reports indicating power went down at a subset of reporting power meters during a time duration is received, at a monitoring facility. The plurality of reporting power meters receive power from a lateral power feed receiving power through an Automatic Lateral Switch. A respective power restore report indicating power is restored at the respective reporting power meter is received within a recovery time duration after receiving each respective power down report. Based on receiving the respective power restore report within the recovery time duration, an occurrence of an Automatic Lateral Switch operation which includes operating contacts providing power to the lateral power feed by the contacts opening and remaining reclosed is determined. Based on determining the Automatic Lateral Switch operation, an indication of the Automatic Lateral Switch operation is stored into a database system.

  • Publication number: 20200354296
    Abstract: Use of diverse biomass feedstock in a process for the recovery of target C5 and C6 alditols and target glycols via staged hydrogenation and hydrogenolysis processes is disclosed. Particular alditols of interest include, but are not limited to, xylitol and sorbitol. Various embodiments of the present invention synergistically improve overall recovery of target alditols and/or glycols from a mixed C5/C6 sugar stream without needlessly driving total recovery of the individual target alditols and/or glycols. The result is a highly efficient, low complexity process having enhanced production flexibility, reduced waste and greater overall yield than conventional processes directed to alditol or glycol production.

  • Publication number: 20200270942
    Abstract: A motorized window treatment system may include a roller tube, a covering material windingly attached to the roller tube, and a drive assembly that may be at least partially disposed within the roller tube. The drive assembly may include a motor having a drive shaft that is elongate along a longitudinal direction and a drive gear attached to the drive shaft such that a toothed portion of the drive gear is cantilevered with respect to the drive shaft. The drive assembly may include a gear assembly having a pair of intermediate gears on opposed sides of the drive gear. Rotation of the drive gear may be transferred through the pair of intermediate gears, a connecting gear, a planetary gear set, a cage, and an idler to the roller tube. Rotation of the roller tube may cause the covering material to move between an open position and a closed position.

  • Publication number: 20200217133
    Abstract: A motorized window treatment may provide a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment may include a covering material (e.g., a cellular shade fabric or a roller shade fabric), a drive assembly for raising and lowering the covering material, and a motor drive unit including a motor configured to drive the drive assembly to raise and lower the covering material. The motorized window treatment may comprise one or more battery packs configured to receive batteries for powering the motor drive unit. The batteries may be located out of view of a user of the motorized window treatment (e.g., in a headrail or in a battery compartment). The motorized window treatment may use various power-saving methods to lengthen the lifetime of the batteries, e.g., to reduce the motor speed to conserve additional battery power and extend the lifetime of the batteries.

  • Publication number: 20200151581
    Abstract: A system and method is disclosed for using AMI smart meter messaging types and data mining decision trees to determine if local equipment failure is present. The system and method may be used to predict impending failure based upon smart meter message behaviors and to create proactive investigation tickets. The predictions models may be generated from a database of smart meter messaging and customer outage reports. The system and method can be applied to detect failures of higher level device equipment and may be incorporated into customer service processes. The system and method may also be used to determine customer owned equipment failures for referral to electricians.

  • Patent number: 10590700
    Abstract: A battery-powered motorized window treatment for covering at least a portion of a window may be adjusted into a service position to allow for access to at least one battery that is powering the motorized window treatment. A headrail of the motorized window treatment may be adjusted to the service position to allow for easy replacement of the batteries without unmounting the headrail and without requiring tools. The motorized window treatment may comprise brackets having buttons that may be actuated to release the headrail from a locked position, such that the head rail may be rotated into the service position. The headrail easily rotates through a controlled movement into the service position, such that a user only needs one free hand available to move the motorized window treatment into the service position and change the batteries.

  • Publication number: 20200032582
    Abstract: A manual drive assembly for a manually-operated window treatment based on a drive chain formed as a loop, may incorporate one or more intermediate tensioners disposed between two ends of the loop. The loop may be formed between a manual clutch mechanism coupled to the window treatment and an end tensioner. The one or more intermediate tensioners may serve to limit slack in the loop such that sides of the loop cannot be pulled to create a large loop, for example, having a gap of four inches or greater, between the hanging sides of the cord.

  • Publication number: 20200003006
    Abstract: A window treatment retention system may include a roller shade assembly and one or more retention brackets that at least partially enclose the roller shade assembly and do not interfere with operation of the roller shade assembly. The retention brackets may be configured to absorb an impact force associated with detachment of the roller shade assembly from a mounted position. The retention brackets may deflect upon absorbing the impact force, and may limit displacement of the detached roller shade assembly from the mounted position. The retention brackets may deflect such that the roller shade assembly does not pass through openings defined by the retention brackets. The retention brackets may deflect such that the width of at least one of the openings defined by the retention brackets does not expand beyond a distance that is equivalent to the diameter of a roller tube of the roller shade assembly.
